how much does he want? how much boost are you running? IIRC the stock fuel pump can handle 10-12psi reguardless of injector size, 450's and 550's arent exactly small per say, adding 720's to the mix isnt going to change the maxium output of the stock fuel pump, i say, ride this dude for as much as you can get the price down, because cmon, if your going to sell a car, make sure it works first.
A few things you might want to check is to make sure the pump is getting a good voltage signal
FUEL FILTER would definalty be one of the things i would check
Pressure check the fuel system, even though the pump may be getting a good voltage reading, it could be tireing out and going bad, by the sounds of your mods it seems fitting for a new pump would help your tuning greatly
lastly, goodluck
